Answer: The main abiotic reservoir for phosphorus is in the soul
Explanation:
Phosphorus cycle refers to the ways phosphorus moves from through lithosphere , hydrosphere and biosphere.
Phosphorus is essential for plants growth and major components of nucleotides in DNA and RNA. It is a major constituent of teeth.
Steps in phosphorus cycle are;
Weathering: the breaking down of rocks into smaller pieces. Rock is the major source of phosphorus.
Other sources of phosphorus is from phosphate fertilizers which is applied to the soil to be absorb by plant.
Absorbption of phosphorus: plant absorb phosphorus in the soil which is use for plants growth. Some phosphorus can be washed into the water system which is use by plants and animals there.
Return to the environment through decomposition: when plants and animals die, microbes acts on them and bring about decomposition. When they are decomposed,phosphorus is released into the environment.
